 " Iris carmine, bill and feet black." 

 Common on all the islands and on the adjacent coast. 

 Regarded as a species in the old-fashioned sense, this King 

 Crow, ranging as it does over the whole oriental region, probably 

 exhibits greater variation than almost any other species within 

 the area. 



While it is indubitably true that too many nominal 

 species have been founded on material deficient both in num- 

 bers and in range, the converse is undoubtedly true and at the 

 present time it is not possible to maintain that only one 

 species can be maintained. Without going into the whole 

 question, which the material at my disposal does not admit of, 

 it may be stated that so far as material from Java, Borneo, 

 Sumatra and nearly the whole length of the Peninsula shows, 

 we can recognize the following forms. 



1. A form with a fairly full, compressed and recurved 

 crest with large rackets and a wing of more than 150 mm. = 

 Dissemurus paradiseus paradiseus (Linn.). 



Tenassenm, Northern two-thirds of the Malay Peninsula, 

 Southern Siam, Sumatra and Java. D. icinguoncnsis, Gould, 

 is probably synonymous. 



2. A form with the crest less developed, slightly shorter 

 wing and smaller rackets = Dissemurus paradiseus platurus 

 (Vieill.) 



Inhabits the extreme smith of the Peninsula, the Rhio 

 Archipelago, Java and Sumatra and is connected with the fore- 

 going by intermediate specimens in the central third of the 

 Peninsula. 



3. A still smaller form, wing about 140 mm., tail rackets 

 still more reduced and with practically no crest = Dissemurus 

 paradiseus brachyphorus, lip. Inhabits Borneo.
